/ ooINsE'LEcTING DEVICE.

T0 alt lwhom t may concern .Be it known that I, FRANK BURTON, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have vinvented certain new and useful Improvements in Coin-Selecting Devices; and I do declare the following to be a full, clear, and exact description of the vinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acy companying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to a coin selecting device especially adapted for use in connection with telephone pay stations but adaptable for other purposes, and consists in the construction and arrangement of parts hereinafter more fully set forth and pointed out particularly in the claims.

The object of the invention is to provide' simple and efficient means for gaging and selecting coins used in pay station telephones, and in coin controlled and coin actuated machines, whereby spurious coins will be allowed to either pass harmlessly through the device or will be arrested therein and discharged therefrom without becoming effective in actuating the mechanism.

The above object is attained by the con struction illustrated in the accompanying drawings, in which f Figure 1 is a side elevation of one of the side plates which form the case into which the coins are introduced, and in which the calipers or gaging and selecting devices are located. Fig. 2 is a similar view showing in section a portion of the coin receiving box of a telephone pay station to which'the coin selector is attached. Fig. 3 is a view similar to Fig. 2, showing how a coin larger than a nickel tive cent piece will be arrested inthe device and discharged therefrom. Fig. 4: is a transverse section through the complete case as on line 4 4 of Fig. 1. Fig is a horizontal section through the complete case as on. line 5 5' of Fig. 1. Fig. 6 is a fragmentary view in horizontal section showing the spring returned shaft carrying a knurled disk through the medium of which said shaft may be actuated to swing the pivoted gage or caliper member.

Referring to the drawings by the characl ters of reference marked thereon, 1 and 2 Specification of Letters Patent.

designate the side pieces, respectively, which form the coin receiving case, the inner faces of which are provided with ribs or raised marginal portions 3, which, when said plates are placed together, coperate to space the plates suiiiciently to allow of the disposition of the operative parts therebetween and to afford gaging passages for the passage of the coins. At the top of said plates said co operating ribs extend inwardly, as shown at f1, to form a centrally disposed gaging openmg 5 communicating with the interior of the case. Said opening is in the form of a slot which is of such length and width as to admit of a coin but little larger in diameter and thickness than a nickel five cent piece. The gaging slot 5 communicates with a chamber 6 within the upper portion of the case into which a coin which is introduced into the opening 5 will fall.y At the bottom of said chamber 6 is a gaging slot 7 formed by the walls of the side pieces of the case,the inwardly extending portions 8 of the dividing ribs, and the interposed blocks 9. This gaging slot 7 is of the exact length and width to correspond with the diameter and thickness of a nickel five cent piece so that should a nickel or a coin corresponding in size thereto be introduced into the case through the opening 5 it will pass through the gaging slot 7 into the lower chamber 10. Within said chamber 10, and pivoted at 11 between the side pieces 1 and 2 is a swinging caliper or gaging member 12 in the form of a bar or arm, which is provided with a slot 13, that, in length is somewhat less than the diameter of a nickel live cent piece.v This swinging caliper or gaging member normally lies in a horizontal position within the chamber 10, and is adapted to swing in the arc of a circle Aupon the fulcrum or pivot 11 consisting of a shaft which projects at one side of the case and carries a knurled thumb wheel 111. Extending inwardly from said wheel is a hollow hub or sleeve 15 (see Fig. 6) which embraces the shaft 11 and forms alhousing for the coil spring 16 which is wound abouty said shaft, and one end thereof is made fast to the side piece 1 of the case, while the other end is secured to the shaft by the transverse pin 17. By this arrangement the pivoted gaging member 12 may be swung upon its pivot by rotation of the thumb wheel, and when said wheel is released will be returned to its normal position by the action of the spring 16. rJlhe sides of the slotted opening 13 in the pivoted gaging member 12 are beveled, as shown at 1S, to assist in directing` a coin into said slot.

The parts are so disposed that a coin passing through the slot 7 will be directed into the slot 13 in the gaging member 12. 1f the coin be of the proper diameter it will lie in said slot 13 in position to be discharged therefrom as the pivoted gaging member is actuated through a manipulation of the lrnurledwheel 14 hereinafter explained.

Pivoted in the outer end of the gagingI member 12 is a dog 19. This dog is provided with a tail piece 20, which. as the cali--l per or pivoted gaging member 12 isswung on its pivot, will engage the periphery of the coin lying in the slot 13 in said member. At the free end of the dog 19 is a head piece 21, and between said head piece and the piv- Oted central portion of the dog is a notch 22. A stop pin 23 is mounted in the pivoted portion of the dog and adapted to engage the end of the gaging member 12 to prevent the dog swinging upwardly out of position.

When a coin of the correct thickness and diameter is introduced into the case through the slot 5 it will pass through chamber G and through the slot 7 into chamber 10` falling through said ychamber 10 into the slot 13 in the pivoted member 12 wherein the coin will be arrested, as shown at 24 in Fig. 2. In this position of parts by a rotation of the knurled wheel 14 the pivoted gaging member 12 may be swung upwardly in the arc of a circle, as shown by solid lines in Fig. As said member is swung upon its pivot the dog 19 will swing on its fulcrum by gravity, so as to -.cause the tail piece 20 thereof to bear against the periphery of the coin, as shown in said last mentioned figure. At the limit of the upward movement of the member 12 the block 9 will enter the notch 22 in the dog and arrest its free end and cause it to swing farther on its pivot and carry the tail piece thereof forcibly against the coin, so as to eject the coin from the slot in the pivoted member 12, as shown by dotted lines in Fig. 2.

This device is shown in connection with the coin box 25 of a telephone pay station which is provided with an aperture 26 in the wall thereof, over which the case is secured through the medium of the flanged brackets 27 mounted on the sides thereof, so that upon a coin being discharged from the pivoted gaging member it falls into said box and may then be directed into a suitable chute or guide, not shown, for any desired purpose.

Projecting at right angles from the pivoted gaging member 12 at the pivoted end thereof is a guard member 28 which normally occupies a Vertical position, and serves as a guard to prevent the possibility of a coin accidentally passing through the opening 26 into the box 25, after falling through the opening 7. Should a coin be deposited in the case too small in diameter, instead of lodging in the pivoted gaging member 12 it will pass therethrough and fall from the case through the slotted opening 29 at the bottom thereof, as shown by dotted lines 30 in Fig. 1. After the coin has been discharged from the pivoted gaging member by manipulation of the knurled wheel 14, as shown in Fig. 2, upon releasing said wheel the spring 16 will return the gaging member to its original horizontal position. Then returning to said horizontal position the pivoted dog 19 will strike the lug 31 projecting frrm the wall of the case in the path thereof. and will be swung on its pivot so as to retract the tail piece 20 thereof and preventy it projecting into the slot or passage 2f) in a manner to afford an obstruction to the free passage of a coin therethrough.

It will be noted on referring to Fig. 2 that as the pivoted gaging member is swung upwardly the free end of the dog 19 will pass through the opening 't' and extend into the chamber G. The purpose of this is to sweep from the chamber G a coin which might be lodged therein because of the fact that it is too large in diameter to pass through the opening 7 as illustrated at 32 in Fig. 3, said coin in this operation, by reason of the engagement of the dog therewith, being discharged through the slotted opening 33 in the rear edge of the case, as illustrated by dotted lines in said last mentioned figure.

Because of the fact that the pivotcd coin gage or caliper 12 is formed of a single piece through which the slot 13 of correct proportions passes, said gage is not liable to become ineffective for gaging coins because of wea r through continual use. rendering the device serviceable for an indefinite period. It. will further be noted that the sides of the case are formed of integral pieces wherein the various gaging slots or apertures are produced by milling said parts. enabling absolute accuracy to be obtained in the dimensions thereof, and providing against variations with respect to said dimensions` through wear or the improper disposition of movable parts.
